December 14,2011 :  A new Novomatic 5-reel, 20-payline online slot game "The Rainbow King" featuring three bonus games has gone live at Sky Vegas.
 
Landing three or more King icons triggers a Rainbow King Feature, where the player moves a character over the game board by throwing dice, and can achieve different winnings on each square.
 
Three crown symbols on reels 2, 3, 4 activate the "King Cash" feature. With twelve crowns to choose from – only one hides the jackpot.
 
Last but not least the Cash Castle Feature – triggered by three or more castle symbols – allows the player to choose a castle to reveal rewards.
